WILLIAM S. FOSTER, OF DALLAS, WISCONSIN.

ROAD-PLANER.

Application filed. March 10, 1919.

To all 10. mm it may concern Be it known that I, IVILLIAM S. FOSTER, acitizen of the United States, residing at Dallas, in the county ofBarron and State of lVisconsin, have invented new and usefulImprovements in Road-Planers, of which the following is a specification.

The primary object of this invention is to provide an improvedroad'finishing device, which is particularly adapted to plane 01ftransverse ridges in roads rendering the surface of the road plane.

It is an especial object of my invention to provide an improved planingtool for such a machine; and to provide improved means for mounting theteeth used in the machine.

Ti Vith these and other objects in view, my invention is disclosed inthe accompanying drawings, in which- Figure 1 is a top plan of myinvention; Fig. 2 is a side elevation of same, partly in section; andFig 3 is a section on line 33 of Fig. 1.

Referring to the drawings, I provide a long runner 1, and short runners2 and 3. Runners 1 and 2 are provided with downwardly turned ends to cuta path for the runners. Runners 2 and 3 are connected by a suitableU-shaped or V-shaped brace 4, such as shown in Fig. 2. I provide aplaning tool 5 extending diagonally from runner 1 to runner 3, tocut-out portion 10 of which its angular portion 17 is attached orengages, being secured to the runner by a suitable bracket 18. Planingtool 5 is provided with cutting blade 6, of steel sharpened and turnedslightly to the front to shave oil the high places and send the dirt tothe side and center of the road, where it will pass under the inclinedplaning tool, thus crowning and shaping a fine grade. I provide suitablebraces or cross-ties 7 and 8, between which are mounted a series ofteeth 9, secured by the bolts 10, as illustrated. I further providesuitable cross pieces or stays 11 to brace the runners. At the rear ofthe machine I provide planks 12, a seat 14, and

. steering or manipulating handles 15, by

means of which the operator may assist in guiding the device whenturning the machine around. The runners 1 and 2 are provided withprojecting ends 13 to cut a groove in the road for the runners and tokeep the machine from sliding sidewise.

Suitable draft mechanism 19 is attached Specification of Letters Patent.

to the forward ends of the runners to which horses may be hitched topropel the device when in use; but it is within the contemplation of myinvention to operate same by any suitable motive power.

In operation the ends 13 of the runners cut grooves for the runnerswhile the device is being drawn ahead and prevent the plane from slidingsidewise. The harrow teeth, which are adjustable to the desired depth bymeans of the bolts 10, serve to break up the ridges in the road so thatthe planing tool will cut the ground smoothly, and the planing toolbeing mounted in inclined position relative to the plane on whichrunners 1 and 3 travel, planes the earth and guides same toward thecenter of the road, thus shaping a fine grade in an eiiicient manner.The planing tool extends to some distance beyond runner 3, as shown, andis elevated somewhat above the bottom edge of that runner, preferably asillustrated in Fig. 2. The runners 2 and 3 are connected by a suitablebrace which serves to keep them in proper alinement.

It is within the contemplation of my invention to suitably modify any ofthe details of construction herein disclosed, the apparatus illustratedbeing that which I now consider to represent the best embodiment of myinvention.

lVhat I claim is:

1. In a road planer, the combination of a long runner, alined spacedshort runners parallel to the long runner, an upwardly arched braceconnecting the short runners, an inclined relatively short and rigidlymounted planing tool, having its inner end attached to the long runner,and having its outer end projecting substantially beyond the shortrunners, said planing tool extending from substantially the bottom edgeof the long runner to a slightly elevated position relative to the shortrunners, whereby to send the dirt toward the side and center of the roadwhere it will pass under the inclined planing tool and shape a finegrade.

2. In a road planer, the combination of a plurality of parallel runners,a relatively short and rigidly mounted planing tool at tached at one endto one of the runners and extending substantially beyond the otherrunner, said planing tool being positioned in upwardly inclined relationto the runners from the point of attachment to the first mentionedrunner, and a harrow element carried by the road planer in advance ofthe planing tool, said harrow element having means for verticaladjustment of the-harrows, for the purposes described. 7 i

3. In a road planer, the combination of a plurality of longitudinallya'lined and spacedrunners athird parallel runner; an upwardly inclinedrelatively short diagonally mounted planing tool rigidly attached totherunners and extending beyond the runners of the machine on one sideonly; cross braces connecting the runners with each other, an archedbrace connecting the spaced longitudinally alined runners over theplaning portion of the machine, a plurality of harrow supporting bracesarranged inadvance of the planing tool, and harrows adjustably mountedtherein.

. 4. In a road planer, the combination of a plurality of parallelrunners a relatively short rigid planing: tool, a spaced runner alinedwith one of the afore-mentioned runhers and to which the planing tool isafiixed in diagonal and elevated relation to the parallelrunner on theopposite side of the.

machine. and past which it extends, cross braces connecting the runnerswith each other, the aforesaid planing tool being removable, and harrowteeth arranged in staggeredrelation in cross braces in advance of theplaning tool, and forwardly projecting teeth at the forward end oftheparallel runners to shape thegrade, substantially as described.
